Answer: All living things move in some way. This may be obvious, such as animals that are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun. All living things grow. Earthworms hatch from eggs and can grow up to a metre or more in length! Some earthworms are also able to regrow small parts of their body that have been lost or injured.  Chromists are a diverse group of plant-like organisms and range from very small to very large. They are found in almost all environments.
